Research Scenario Hypertension is defined as a systolic blood pressure (SBP) of 140 mmHg or more, or a diastolic blood pressure (DBP) of 90 mmHg or more. Diastolic blood pressure (DBP) measurements from the general population form a normal distribution with m = 82 mmHg and s = 10 mmHg. Epidemiological studies have shown that obesity increases the risk of hypertension (high DBP). Using data from a cohort study, a researcher obtained a sample of n = 144 obese persons...
